Rendezvous Printer With Airport Express


I don't know what Rendezvous is but I know it has something to do with setting up my printer with an Airport Express hub.

I have my iMac g5 connected to an Airport Express hub through the LAN port. (The connection is working fine). The Epson R300 printer is connected to the Airport Express hub through the USB port. I can find my printer in the print dialog box under Rendezvous printers, but when I try to print the print job status says "Printing" but nothing prints.
Do you have the latest airport software and Airport Express Firmware?
And the latest Epson driver download? FYI- The Epson update requires two or three downloads/installs.
